This study investigates the test-retest reliability of consonant-nucleus-consonant (CNC) word and phoneme scores in cochlear implant (CI) users. Researchers established reliability bounds, indicating the expected variability in scores over repeated testing. Understanding these bounds is crucial for accurately interpreting changes in speech performance for individuals with CIs. The findings offer valuable insights into the consistency of speech assessments in this population. By quantifying the expected range of fluctuation, clinicians can better discern genuine improvements or declines in speech intelligibility from natural test-retest variability. This research directly impacts how speech perception in CI users is measured and understood, contributing to more precise clinical evaluations.
